Abstract

A stripper for a can drawing and ironing device can remove a drawn and ironed can material from a punch without causing buckling (curl and wrinkle) on the material. Each finger (2) is split into three small fingers (21), and an axial end of each small finger (21) is engaged with the lower part of a rocking arm (3) with an elastic member (24) in between. A head section (33) of each rocking arm (33) is engaged with a cam section (42) of a cam ring (4) to allow the finger (2) to be driven independent of each other. Each rocking arm (3) is urged by an arm spring (32) in the direction of opening the small finger (21), while the small finger (21) is urged by a finger spring (22) in the direction of its closure.
